Eponym | Alan T. Waterman |
Waterman is a lunar impact crater that is located on the Moon's far side, and cannot be viewed directly from the Earth. It lies along the southern outer ramparts of the prominent crater Tsiolkovskiy. Almost attached to the southwest is Neujmin, so that Waterman lies straddled between these two features.
The outer rim of Waterman has been somewhat modified by its proximity to Tsiolkovskiy to the north, and it now has a slightly oval shape. The rim edge is worn and irregular, and ejecta material has been carried into the northern interior floor. There are a pair of lower albedo patches in the southern interior, which are typically characteristic of basaltic-lava deposits. A few low ridges lie about the center and also to the east of the midpoint.
The crater was named after American physicist Alan T. Waterman by the IAU in 1970. [2]
Aitken is a large lunar impact crater that lies on the far side of the Moon, named for Robert Grant Aitken, an American astronomer specializing in binary stellar systems. It is located to the southeast of the crater Heaviside, and north of the unusual formation Van de Graaff. Attached to the southwest rim is Vertregt. To the southeast is the smaller Bergstrand.
Proclus is a young lunar impact crater located to the west of the Mare Crisium, on the east shore of the Palus Somni. Its diameter is 27 km. It was named after 5th century Greek mathematician, astronomer and philosopher Proclus.
Tsiolkovskiy is a large lunar impact crater that is located on the far side of the Moon. Named for Russian scientist Konstantin Tsiolkovsky, it lies in the southern hemisphere, to the west of the large crater Gagarin, and northwest of Milne. Just to the south is Waterman, with Neujmin to the south-southwest. The crater protrudes into the neighbouring Fermi, an older crater of comparable size that does not have a lava-flooded floor.
Apollo, also called the Apollo basin, is an enormous impact crater located in the southern hemisphere on the far side of the Moon. This formation dwarfs the large crater Oppenheimer that is located next to the western rim. The crater Barringer lies across the northern wall. To the southeast is the crater Anders, and Kleymenov is just to the east of the rim.
Bowditch is a lunar impact crater that lies on the far side of the Moon, just beyond the eastern limb. It is located on a region of the lunar surface that is brought into view due to libration, but at such times the area is viewed from the edge and so not much detail can be observed. It lies just to the north of the small Lacus Solitudinis lunar mare, between the craters Titius to the southwest and Perel'man to the east-northeast.
Fermi is a large lunar impact crater of the category named a walled plain. It was named after Italian-American physicist and Nobel laureate Enrico Fermi. It lies on the far side of the Moon and can not be viewed from the Earth. Thus this feature must be viewed from an orbiting spacecraft.
Oppenheimer is a large lunar impact crater that lies on the Far side of the Moon. It lies along the western outer rampart of the immense walled plain Apollo. Nearby features of note include the dark-floored crater Maksutov to the southwest, and Davisson to the west-southwest. The latter intrudes into the eastern rim of Leibnitz, a feature about 20% larger than Oppenheimer.
La Pérouse is a lunar impact crater that is located near the eastern limb of the Moon. It lies northwest of the larger crater Ansgarius, and to the east of Kapteyn. This crater appears foreshortened due to its location, but the rim is nearly circular when viewed from orbit.

Widmannstätten is a lunar impact crater in the southern part of the Mare Smythii, near the eastern limb of the Moon. The rim of this crater has a wide gap along the western side, where it is joined to the larger Kiess. There is also a gap in the northern rim where the crater floor is joined to the adjacent lunar mare. The dark interior floor of this formation has been flooded by lava, leaving a level interior surface and a shallow surviving rim.
Chauvenet is a lunar impact crater that is located to the northeast of the prominent crater Tsiolkovskiy on the far side of the Moon. Less than one crater diameter to the northwest of Chauvenet is the crater Ten Bruggencate.
Runge is a lunar impact crater in the Mare Smythii, along the eastern edge of the Moon. It lies less than one crater diameter to the north-northwest of the very similar crater Warner. To the west-northwest is Haldane, and due west is the smaller Talbot.
Warner is a lunar impact crater that is located in the southern part of the Mare Smythii, near the eastern limb of the Moon. In this location the crater is viewed almost from the edge from Earth, and is sometimes hidden from sight due to libration. The crater lies just to the south-southeast of the very similar Runge. To the southwest is Widmannstätten, and to the south is the merged Kao–Helmert crater pair.
Dobrovolʹskiy is a small lunar impact crater on the Moon's far side. The northwest part of its rim is intruded upon by the somewhat larger crater Shirakatsi, and the outer rampart of that feature covers most of the interior floor of Dobrovolʹskiy. Very little of the original floor now survives, with a small section near the southern inner wall. The remainder of the crater rim is somewhat circular and only mildly worn.
Patsaev is a lunar impact crater that lies on the far side of the Moon, to the northeast of the prominent crater Tsiolkovskiy. To the northwest is the smaller crater Lander.
Litke is a lunar impact crater that lies within the large walled plain Fermi, near the north-northwestern inner rim. Less than one crater diameter to the west-northwest is the slightly larger Delporte. Litke is located on the far side of the Moon and cannot be viewed directly from the Earth.
Volkov is a lunar impact crater on the Moon's far side. It is located to the north of the prominent crater Tsiolkovskiy, and east-southeast of Dobrovol'skiy. Overlying the southeastern rim of Volkov is the satellite crater Volkov J, and the two have merged to form a figure-8 shape. The crater Lander is attached to the southwest rim of Volkov J, making this a triple-crater formation.
Neujmin is a lunar impact crater on the Moon's far side. It is nearly attached to the west-southwest of the smaller crater Waterman, and lies to the southwest of the prominent Tsiolkovskiy.
Shirakatsi is an impact crater that is located on the Moon's far side. It is attached to the southern exterior rim of the larger crater Perepelkin, and overlies the northwestern rim of Dobrovol'skiy.
Langemak is a prominent impact crater on the far side of the Moon. It is located less than one crater diameter west-northwest of Danjon, and nearly due east of Meitner. To the southwest of Langemak is Kondratyuk. Langemak partly overlies the larger and older crater Langemak N. This feature is also attached to the northeastern rim of Kondratyuk.
